FAQ – Frequently asked questions
Electricity consumption/ Electricity bill
When comparing temporary ones, you would need to know approximately your own annual consumption (kWh). The profitability of exchange electricity is affected by the possibility of using cheaper usage hours.
External batteries are expensive and have a small capacity. In addition, most electric cars do not yet have the possibility of two-way use.
Exchange electricity is recommended, if it is possible to use cheaper night electricity.
Hourly electricity consumption data can be found at www.data.fingrid.fi/fi/dataset/electricity-consumption-in-finland
Yes, the cheapest hours of exchange electricity are usually between 00:00 and 05:00.
At the very least, the devices cut out the most expensive operating hours, more advanced ones can also have temperature monitoring. In this case, the activity is focused on cheaper classes, weather permitting.
Currently, exchange-traded electricity can be the most profitable (Tampere 2022).
A sensible enclosure does more good than harm; the most important thing is protection and sufficient “clearance” outside the outdoor unit, so that the incoming and outgoing flows do not mix too much with each other.
Usually, the device’s own thermostat shuts off the device when the room temperature exceeds the thermostat setting. A running ILP helps spread the heat of the hearth.
In the cooling function, the main thing is to lower the temperature, in drying, the internal temperature cools down a little when the moisture is removed.
In severe frosts, newer devices can turn themselves off, and some models have an internal timer that you can take advantage of. Timing through the socket is not recommended.
Basically, you should prefer a newer and more energy-efficient machine. Actual rotation between the machines is not recommended, the compressor speed is adjusted as needed, and the compressor also wears out from starting times.
The use of ILP is recommended in mild weather, only fireplace heating in the cold season.
The device’s thermostat adjusts the operation according to the room temperature. During fireplace heating, the internal temperature of the ILP can be lowered by a couple of degrees, or not changed at all.
The temperature can be lowered to 16 degrees during the absence, and an additional heater that ensures operation, e.g. an electric radiator, to 12 degrees. Check before departure that the indoor and outdoor units are ok and clean.
Heat distribution systems
The reaction speed is affected by how deep the heating cable is (2cm/5cm). In terms of energy saving, optimizing heating is always profitable.
Yes, if it is electric heating. In a water circulation system, it is advisable to always keep a small circulation on, so that the piping does not freeze.
The cheapest hours of exchange electricity are usually 00–05, and the heating can be controlled for this time with clock switches, a smart thermostat or manual implementation.
Although the radiator produces air temperature with less energy, floor heating heats and thus dries the room more evenly. The use of night electricity is recommended.
Level and time are affected by structures, heating power, installation depth, electricity price.
